* Generate redacted event enums and implement corresponding event structs * Enable the *EventContent derives to generate redacted events Most redacted event code is now generated by the *EventContent derive macro. The exception are any content structs with the custom_redaction attribute. This leaves implementing up to the user. * Add redact method to Redaction/CustomEventContent * Add accessor methods for redacted event enums * Add RedactedEventContent trait and super traits to match EventContent
